Don't even try to force it. Figure on rebuilding the brake system, clutch hydraulics, cooling system, fuel system, struts, weatherstripping, tires, wiper blades, battery, recalls, and electrical system updates. Once you get the car to drive you will find other items to fix like window motors, speedometer, door adjustments, antennae, etc. It is possible the clutch mechanism itself is stuck. If it is rusted up enough you may have to remove the transmission and clutch and clean it up to make it work. That's why any estimate is only an estimate, it is impossible to know exactly what needs to be done to a "sleeper".

Having sat that long, I am surprised the brakes are also not seized. Sounds like you need new clutch hydraulics.
The stock clutch line is plastic, it is a highly recommended update to switch it out to a stainless line as well.

The short answer, the master cylinder for the clutch is probably seized.

Much more likely the disc is seized to the pressire plate and flywheel. Sometimes it can be forced free by bump starting but you need a running engine to do that. Even then it will likely chatter afterward and need replacing. I'm flying into San Jose Monday and going on to Vacaville. Perhaps I could take a look and advise you better if there's time. You're in Brentwood correct?

If you cannot press the clutch pedal down or if you don't even have hydraulic function, you will have no way of knowing that the clutch/plate is seized unless you put it in neutral and try to roll it and find it wants to turn the engine. This isn't a clutch system that uses a cable or manual linkage. It is a hydraulic system and without hydraulics/fluid/operating master and slave cylinders- you cannot do much of anything.

Im able to put it in neutral... and it rolls free without attempting to turn motor
